What exactly does IP mean?

IP is a unified address format provided by IP protocol, which assigns a logical address to every network and every host on the Internet to shield the difference of physical addresses. Common IP addresses can be divided into IPv4 and IPv6. At present, there are some ip proxy software, but most of them are charged.

For example, the IP address of a networked computer is:110100100100100/kloc-0.

For the convenience of memory, people divide the 32-bit binary that constitutes the IP address of a computer into four segments, each segment has 8 bits, separated by decimal points, and then convert every 8-bit binary into decimal numbers, so that the IP address of the computer above becomes: 2 10.73. 140.2.

Classification of IP addresses:

1, static IP address?

It means that each computer is assigned a fixed IP address, which has the advantage of easy management, especially in the local area network where network traffic is limited by IP address. Management is based on fixed IP address or IP address grouping.

It can avoid the complicated identity authentication process that users have to go online every time when charging in user mode, and also avoid the embarrassment that users often forget their passwords. A static IP address is an IP address assigned to a computer or network device for a long time. Generally speaking, computers that use private lines to access the Internet have fixed IP addresses.

2. Dynamic IP address

Computers that access the Internet through modems, ISDN, ADSL, cable broadband, cellular broadband, etc. Assign IP addresses only when necessary. Every time you surf the Internet, Telecom will randomly assign an IP address, which is different every time. This is a dynamic IP address. Because IP address resources are precious, most users surf the Internet through dynamic IP addresses.

The basic format of IP:

1. The current IP network uses 32-bit addresses, which are expressed in dotted decimal system, such as192.168.0.1. Address format: IP address = network address+host address or IP address = network address+subnet address+host address.

2. The network address is assigned by ICANN, including InterNIC for North America, RIPENIC for Europe and APNIC for Asia-Pacific region, so as to ensure the global uniqueness of the network address. The host address is assigned by the system administrator of each network.
